Enable: When ticked, causes this service instance to start automatically when
the system is re-booted. If this check-box is cleared, the service will need to
be started manually (from the “Control” → “Services” menu)
Delete: Causes the configuration for this instance to be removed from the
system when the form is submitted.
Server hostname / IP address: By default, the service instance will listen for
incoming connections on all available interfaces. If this field is populated
with an IP address, the instance will only listen for connections addressed to
the specified IP address. This option is only useful on systems with multiple
IP addresses.
Server port/service name: This field specifies the port on which the service
instance listens for incoming connections. The port can be specified as either
a name or a number. The mapping from port names to port numbers is
configured by the conventional Linux file /etc/services which can be
edited from the command line if required.
